The package manager won't display it, nor there is there a Yama package, so it must be built-in, because I have the folder /proc/sys/kernel/yama. @slm I've already tried that solution and it didn't work. I'm not trying to attach to a process - I fail when I let GDB spawn the process.

Suspending the global KDE&X-Windows keyboard shortcuts while specific application is runningThe "special window" worked and the "special application" didn't."special window" also has matching, so it still works whenever I reopen Emacs. As for the layout switching - I can't set it via the global shortcuts, since it involves only modifier keys(Alt+Shift) and the global shortcut mappings must have at least one regular key. I had to set it via "Input Devices"=>"Keyboard"=>"Layouts"
